Why on earth would police put handcuffs on a man walking a large dog at a Queen's Park rally of something called Al-Quds Day? Neither Cupcake, nor Einstoss, were intent on provoking trouble at the Muslim rally which over the years it's increasingly become a "hate Israel" outpouring.
Aside from the fact that Einstoss was merely walking his dog, for cops to side with protestors over those they see as counter-protestors, is a violation of everything the police should stand for. Peace at any price is bad value in a democracy.
